'96 Johnson 88 spl... always has run fantastic including low trolling speed. Now, it will not run at low RPM's but still runs great at higher RPM's (say above 2500k).
Background for what it's worth:
Last fall could not inject the fogging oil due to the shrader valve not operating properly (oil just ran over side of engine instead of inside, valve not opening obviously) but engine started and ran great all year so far up until last week. I run it weekly.
2 weeks ago I ran "out of gas." Primer bulb would not pump up and I put 2 gallons in it after getting towed in and primer bulb pumped up fine. Figured just a bad gas gauge.
Next time out it started fine cold but then began immediately with the stuttering and stammering at low RPM's. Sounds like it's running on 1 cylinder and the rest are not firing. Higher RPM's (as stated above) it runs great.
I'm no mechanic but is it worth it to put in carb cleaner and then replace plugs or just take it in to a pro? If it might be worth putting in carb cleaner (here's where I get all you mechanics pounding the desk) how do I access the carbs to squirt in the cleaner? :facepalm: My understanding is the shrader valve bypasses the carb so you can't squirt the cleaner in there. (sorry but I haven't seen a carbureter since I rebuilt the engine in my Olds442 back in 1969)
Thanx for any advice you've got. I really appreciate this type of forum before handing over my "baby" to someone else but I don't want to do her any harm either.
